OpenGL suddenly stopped working.

A few days ago I've suddenly started having problems with OpenGL. Upon launching the game the scree flashes a few time before going back, the then game crashed if I hit any keys. It was working fine before. I made no changes to my system, all graphics drivers are up to date, and the game loads in dx9 without issue until it hits my ram limit. This is happening in both x64 and x32 KSP.

I can't find anything about this issue online and no other programs on my computer are having any issues.

It's looking like your computer doesn't like OpenGL for some reason. Have you tried running it again without OpenGL to see if it runs?

Some video cards don't like OpenGL. I can't explain why it was working before and not now. Perhaps you received a graphics driver update and now it's not working right.

If you can, please upload the output_log.txt described here: http://forum.kerbalspaceprogram.com/threads/92230-Stock-Support-Bug-Reporting-Guide

I would, however, recommend trying to run the game without OpenGL and reduce your texture resolution to half or less. KSP should still run in under 4 GB of ram unless you're running mods.

KSP Version: 0.25.0.642 Windows 64-bit (Also happens on 32-bit) Steam

What happens: Game refuses to load upon launch when -force-opengl tag is used

Mods / Add-Ons: All Stock

Replicate:

1) Have -force-opengl in Steam's launch options

2) Click play

Result: Immediate crash, game does not even reach loading screen.

For my normal play I use a ludicrous amount of mods and have to run in OpenGL. However since I reverted to stock to attempt to solve this issue and it is still present I'm posting here.

Something bugged me since last night, but wasn`t there still an issue when KSP was installed in the "Program Files" folder and had to be moved out of it or to another drive?

Install all my games by default on D so never had to move stuff.

Usually not a problem with Steam, but it's worth a try. The key is not to move it, but copy and paste to some place with normal permissions, like C:\Games\. The Desktop, Windows, and other protected folders have odd permissions.

Moving it didn't help at all I'm desperate for a solution.

[Claw]

As I said earlier, if it happened all of a sudden then something else on your PC must have changed. Try checking when your video card last updated drivers and try reverting to an older driver. That fixed crashing issues for another person.

The thing is that KSP isn't necessarily going to work great using OpenGL. However, if you were running it fine up until a few days ago, then KSP itself might not be the source of your current problem.

Plus there are a lot of errors in your log. So many in fact that I didn't recognize your original upload as an output_log.txt.

GL: disabling render-to-cubemap due to Radeon driver bugs
GL: disabling mipmapped render textures due to Radeon driver bugs
GL: Detected 0 MB VRAM

GL is reporting 0 MB of video ram, and the log is full of AMD extension errors. So if you truly didn't change anything, I'd start by looking at your video drivers and when they auto-updated last.

Hi there, I apologize for the delayed response but I found a solution! I changed the ksp.exe settings to compatibility mode for Windows 7 even though I have a Windows 7 system and that somehow solved the problem. No clue how but everything's working again. I do appreciate the time you took to help troubleshoot this.

[Master Tao]

Glad to hear you solved it.

Had it been set to compatibility mode for something else?

[NumberNegative]

No. Compatability was blank so the game would run normally but it was before the problem arose. Like I said: my OS is already Windows 7 so I have no idea why Win 7 compatibility mode matters but apparently it does.

you fixed my problem.... thank you. What an ass backwards solution
